I haven't got the sources for these comments - they are just fragments of
memory.
  The increase in Elo rating between S8 and S9 is small - not enough for me to
consider the upgrade. In one set of results that I saw it S9 was +2. Most
results tables put the increase as slightly greater and I have never seen S8
come out higher than S9.

One established correspondance player stated that he used Fritz 8 instead of
Shredder because the "analysis of Shredder is all over the place". I was
intrigued by this statement because I was not sure how an engine with analysis
all over the place got the right answer so often. However I think it is
universally accepted that Shredder analysis is optimistic.

You may want to have a look at Fruit 2.1 if you are looking for consistency in
output. Fruit2.1 is freeware and Fruit2.2 is commercial.
